Default [Q] Xperia J - recover pictures HELP?

Hi everyone!

PLEASE HELP

I have deleted all pictures from phone by my error.

I would like to try recover them by apps for data recovering.

But I have problem, pictures were stored in internal memory (no external sd card)

When I connect mobile to PC and run app for data recover, app cant see mobile memory as external drive

What I need to do that my phone shows internal memory on PC as external drive??

Phone is not rooted.
